[0002] The rear axle assembly of a sedan generally consists of components such as a cross beam, longitudinal arms, bushings, and spring seats. Longitudinal arms are symmetrically arranged at both ends of the cross beam. The longitudinal arms are made of round tubes. One end of the longitudinal arm is welded with a bushing, and the other end is welded with a spring seat. Currently, after the rear axle assembly is welded and formed, it still needs to go through processes such as drilling and deburring, heat treatment, electroplating, etc. These processes are usually carried out in different workshops. Therefore, a transfer vehicle must be used for turnover.

[0003] Although the structure of the existing transfer vehicle is simple, the reliability of positioning the rear axle assembly is poor. During the transfer process, the rear axle assembly is prone to shaking, which is extremely likely to cause surface scratches. Especially when transferring on uneven ground, due to large bumps, the rear axle assembly may fall off the transfer vehicle, which not only affects the transfer efficiency but also has the risk of rework.
